Vue Get Image from URL
Vue Get Image From Url: Vue is a popular JavaScript framework used for building user interfaces. To display images in a Vue application, you can use the img
HTML element and set its src
attribute to the URL of the image you want to display. This URL can be obtained from various sources such as a backend API or from local data.
To fetch images from an API, you can use the built-in fetch
or axios
library to make HTTP requests and get the image data as a response. Once you have the image data, you can display it by setting the src
attribute of an img
element to a base64 encoded data URL or by creating a new Image
object and setting its src
attribute to the URL.
To display images from local data, you can import the image file and set its path as the src
attribute of the img
element. Vue also provides a v-bind
directive to dynamically bind data to an element's attribute, which can be useful when working with dynamic image URLs.

How can I use Vue.js to display an image from a URL?
This code creates a Vue application that fetches images from the Pixabay API and displays them on a web page. The application retrieves images based on search criteria and allows the user to navigate through the images using the previous and next buttons.
The data
function defines several variables that store information about the images, including the image URL, page number, number of images per page, and the total number of hits (i.e., search results).
The mounted
function is a lifecycle hook that runs when the application is mounted to the DOM. It calls the fetchImages
method to retrieve the first set of images.
The fetchImages
method uses Axios to make a GET request to the Pixabay API and retrieves the image URL from the response data. It also updates the total hits variable to reflect the number of search results.
The prevImage
and nextImage
methods allow the user to navigate through the images. The prevImage
method decrements the current image index or moves to the previous page if there are no more images on the current page. The nextImage
method increments the current image index or moves to the next page if there are no more images on the current page.
Finally, the app.mount
function mounts the Vue application to the DOM.
